 is vital and also perform well in extreme environments - both the heat and the cold, outside or inside. Additionally, some portable cords can be water-resistant or water submersible. Because of their characteristics, portable cords are commonly utilized in a range of facilities, such as construction sites, mills, mines, sports complexes, or even marinas.

Varieties

A variety of portable cords, differing in styles, lengths and thicknesses, exist in the marketplace. Common types include Type SJT, SVT, SEOW, SJ, SJOW, SO and SOW. Each has specific applications associated with it. All portable cords are usually comprised of thermoset, thermoplastic elastomer

Thermoplastic

A thermoplastic is a polymer that turns to a liquid when heated and freezes to a very glassy state when cooled sufficiently. Most thermoplastics are high-molecular mass polymers whose Chain s associate through weak Van der Waals forces ; stronger dipole interactions and hydrogen bonding ; or even stacking of aromatic rings ....
. Thermoset cords have heavy-duty-grade rubber jackets and are extremely sturdy. Thermoplastic elastomer cords have medium-duty-grade thermoplastic elastomer jackets and perform well in cold conditions. Thermoplastic cords have a light-duty plastic compound jacket and thus work for light-duty use.

Portable Cord Letter Connotations

The letters used to describe portable cords hold significance. Below are the meanings for each letter.

  • S = 600 Volt Service Cord
  • J = Junior Service - 300 Volt
  • T = Thermoplastic
  • E = Elastomer - thermoplastic that looks and feels like rubber
  • O = Oil Resistant Outer Jacket
  • OO = Oil Resistant Outer Jacket and Oil Resistant Insulation
